The detectability of bars at high redshift: a case study using Euclid-like mock observations of TNG50 simulated galaxies
Gustavo F. Gonçalves, Rubens E. G. Machado, Raquel R. Valença +3
Modern surveys such as Euclid report a decline in the fraction of barred galaxies from the local Universe to , whereas the TNG50 simulation predicts higher bar fractions,…
The response of the inner dark matter halo to stellar bars
Daniel A. Marostica, Rubens E. G. Machado, E. Athanassoula +1
Barred galaxies constitute about two thirds of observed disc galaxies. Bars affect not only the mass distribution of gas and stars, but also that of the dark matter. An elongation…
Bar Properties as a Function of Wavelength: A Local Baseline with S4G for High-Redshift Studies
Karín Menéndez-Delmestre, Thiago S. Gonçalves, Kartik Sheth +10
The redshift evolution of bars is an important signpost of the dynamic maturity of disk galaxies. To characterize the intrinsic evolution safe from band-shifting effects, it is nec…
Chaotic motion and the evolution of morphological components in a time-dependent model of a barred galaxy within a dark matter halo
Rubens E. G. Machado, T. Manos
Studies of dynamical stability (chaotic versus regular motion) in galactic dynamics often rely on static analytical models of the total gravitational potential. Potentials based up…
Bar formation and evolution in disc galaxies with gas and a triaxial halo: Morphology, bar strength and halo properties
E. Athanassoula, R. E. G. Machado, S. A. Rodionov
We follow the formation and evolution of bars in N-body simulations of disc galaxies with gas and/or a triaxial halo. We find that both the relative gas fraction and the halo shape…
Loss of halo triaxiality due to bar formation
Rubens E. G. Machado, E. Athanassoula
Cosmological N-body simulations indicate that the dark matter haloes of galaxies should be generally triaxial. Yet, the presence of a baryonic disc is believed to alter the shape o…
